4. Setup and Installation
The PNI CH2000R PRO Gold is designed for right-side opening doors. Detailed installation steps are provided in the separate installation manual included with the product. Below are general guidelines:
- Prepare the Door: Ensure the door thickness is between 30mm and 50mm. Mark and drill holes according to the provided template for the mortise lock, spindle, and mounting screws.
- Install Mortise Lock: Insert the mortise lock body into the prepared cavity on the door edge and secure it with screws.
- Install Front Panel: Connect the wiring from the front panel (with card reader) to the mortise lock. Position the front panel on the door, ensuring the spindle aligns correctly.
- Install Rear Panel: Connect the wiring from the rear panel to the front panel and the mortise lock. Position the rear panel on the door, aligning the spindle and securing it with mounting screws.
- Install Batteries: Open the battery compartment on the rear panel. Insert 4 new AA alkaline batteries, ensuring correct polarity. Close the compartment.
- Install Strike Plate and Box: Install the strike plate and box on the door frame, ensuring proper alignment with the mortise latch and deadbolt.
- Software Configuration (Optional but Recommended): For full functionality, the lock requires configuration using dedicated software (PNI FLH70, purchased separately). This software allows for card programming, event recording, and room management.

5. Operating Instructions
5.1. Opening with an EM Card
- Present a valid EM proximity card (T5557/Mifare compatible) to the card reader area on the front panel.
- The lock will emit a confirmation sound and/or light indicator if the card is valid.
- Within a few seconds, push down the handle to open the door.
- The door will automatically lock after closing.
5.2. Opening with a Mechanical Key
In case of emergency or battery failure, the lock can be opened using the mechanical key:
- Insert the mechanical key into the keyhole located on the front panel.
- Turn the key to unlock the mechanism.
- Push down the handle to open the door.
5.3. "Do Not Disturb" Function
When the thumb turn on the inside handle is engaged, the "Do Not Disturb" function is activated, preventing external card access. Only mechanical keys can override this function.

6. Maintenance
6.1. Battery Replacement
The lock is powered by 4 AA alkaline batteries, providing approximately 10,000 openings. When the battery level is low, the lock will provide a low voltage alarm. Replace all 4 batteries promptly when this occurs to ensure continuous operation.
- Locate the battery compartment on the rear panel of the lock.
- Open the compartment cover.
- Remove the old batteries and dispose of them responsibly.
- Insert 4 new AA alkaline batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
6.2. Cleaning
Clean the lock surface with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed by drying. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the zinc alloy finish.
7. Troubleshooting
- Lock does not respond to card:
- Ensure the card is valid and correctly programmed for the lock.
- Check if the "Do Not Disturb" function is active from the inside.
- Replace batteries if a low voltage alarm has been indicated.
- Try using a mechanical key to confirm the lock mechanism is not jammed.
- Low Voltage Alarm: The lock will indicate low battery power. Replace all 4 AA alkaline batteries immediately.
- False Closing Alarm: If the door is not fully closed, the lock may issue a false closing alarm. Ensure the door is properly shut and the latch engages fully.
- Open Door Warning: If the door remains open for an extended period, the lock may issue a warning. Close the door to clear the warning.
- Lock mechanism feels stiff: Apply a small amount of graphite lubricant to the mortise lock mechanism. Do not use oil-based lubricants.
